Zero Trust Network Access (ZTNA): Testing Identity-Based Access Controls for Philippine Enterprises

Zero Trust Network Access replaces traditional VPN access with identity-based, context-aware connections to specific applications. ZTNA testing evaluates: identity verification strength (MFA, device posture, contextual signals), policy enforcement (are access policies correctly limiting users to only the applications they need?), bypass potential (can an attacker circumvent the ZTNA broker to reach applications directly?), session security (token handling, session timeout, continuous verification), and the residual attack surface (what's still exposed after ZTNA is implemented?). Many ZTNA implementations leave residual trust paths that undermine the zero-trust promise.
